This is a fantastic collection of WWII Distinctive Unit Insignia for the US Army Airforces during WWII. A distinctive unit insignia (DUI) is a metallic heraldic badge or device worn by soldiers in the United States Army. The DUI design is derived from the coat of arms authorized for a unit. DUIs may also be called "distinctive insignia" (DI) or, imprecisely, a "crest" or a "unit crest" by soldiers or collectors.
